Networked cruise control method of high-speed EMU under transmission delay

In response to the problem of speed cruise control in high-speed EMU, considering the delay of state transmission, and proposed a networked cruise control method. First of all, the high-speed EMU vehicle-speed cruise system is modeling the level linkage system with elastic coupling of the workshop. Secondly, considering the delay problem in the system state sensing, a state-based feedback-based speed control method is proposed. Finally, with the help of the Razumikhin method, the system closed-loop stability was analyzed and the controller design method based on the linear matrix disagreement was given. The proposed method can not only ensure the stability of high-speed EMU speed control system, but also has good control effect. Finally, a numerical simulation example is given, and the results show that the proposed method can reduce the relative velocity by 68.6%.
